(1 point) A thermometer is taken from a room where the
temperature is 20oC to the outdoors, where the temperature is
−12oC. After one minute the thermometer reads 4oC.
(a) What will the reading on the thermometer be after 2 more
minutes?

(b) When will the thermometer read −11oC?
minutes after it was taken to the outdoors.

A thermometer is removed from a room where the temperature is
70° F and is taken outside, where the air temperature is 20° F.
After one-half minute the thermometer reads 60° F. What is the
reading of the thermometer at t = 1 min? (Round your answer to two
decimal places.)
How long will it take for the thermometer to reach 35° F? (Round
your answer to two decimal places.) min

A thermometer is removed from a room where the temperature is
70° F and is taken outside, where the air temperature is 30° F.
After one-half minute the thermometer reads 60° F. What is the

A thermometer is removed from a room where the temperature is
23° C and is taken outside, where the air temperature is −10° C.
After one-half minute the thermometer reads 12° C. What is the
reading of the thermometer at
t = 1 min?

A thermometer at 70 degrees is taken outside where the
temperature is 30 degrees. After .5 minutes the thermometer reads
50 degrees. what is the thermometer reading after 1 minute. (
answer is 40 degrees). using the information from this problem how
many minutes does it take for the thermometer to read 35 degrees?
Round answer to the nearest tenth of a minute.

Suppose that a thermometer is taken from a room that is 14
degrees Celcius and put outside where the
temperature is 6 degrees Celcius.
a) State and solve the differential equation governing the
rate of change of the temperature of the
thermometer with respect to time.
b) After 1 minute the temperature of the thermometer reads 13
degrees Celcius. When will the
thermometer read 8 degrees Celcius?

a thermometer reading 9 degrees c is brought into a
room with a constant temperature of 32 degrees c if the thermometer
reads 16 degrees Celsius after 3 minutes what will it read after
being in the room for 5 minutes? for 10 minutes?

A thermometer reading 8 degreesC is brought into a room with a
constant temperature of 38 degrees C. If the thermometer reads
14degreesC after 2 minutes, what will it read after being in the
room for 4 minutes? For 9 minutes?

a thermometer reading x°C is brought into a room with a constant
temperature of 5°C. if the thermometer reads 15°C after 1 minute
and the thermometer reads 10°C after 5 minutes, what is x°C?

A thermometer reading 6 degrees°C is brought into a room with a
constant temperature of 32°C.
If the thermometer reads 13C after 4 minutes, what will it read
after being in the room for 6 minutes? For 11 minutes?
